Application filed June 22, 190%. Serial No. 439,701.

To all whom it may concern:

Be it known that I, JOHN SoHADE, J12, a citizen of the United States,and a resident of the borough of Brooklyn, county of Kings, city andState of New York, have invented certain new and useful Improvements inSpring. Fastening Devices, of which the following is a specification,accompanied by drawings.

This invent-ion relates to improvements in spring fastening devices forelectrical conductors, and the objects of the invention are to enablethe conductor tobe firmly gripped and maintained in defined position inthe device, to cheapen the cost of manufacture and enable the devices tobe madeout of sheet metal or a combination of sheet metal and wire, andto provide a construction wherein the conductor may be ,insertedlongitudinally into the. device and main.- tained in position.

There are many circumstances in which it is desirable to use a fasteningdevice in which the conductor is inserted longitudinally instead oftransversely, and my device, accomplishes this object as Well as otherobjects which will hereinafter appear.

To these ends the invention consists of a fastening device for carryingout all of the above objects embodying the features of construction,combinations of elements, and

arrangementof parts having the general mode of operation substantiallyas hereinafter fully described and claimed in this specification andshown in the accompany ing drawings, in which-- Figure 1 is aperspective view of a device embodying the invention; Fig. 2 is asimilar view with the wire inserted; Fig. 3 is a perspective view of amodification; Fig. i is a s1milar view with the wire inserted; F1 5 I isa perspective view of another mo ification with the wire inserted; andFig. 6 is a perspective view of a modification with the wire inserted.

The fastening device is adapted to be secured to a base or support A andin this instance the device is shown secured fiat upon the support,although other means of supporting the device may be provided asdesired, according to the nature of the Work for which the device isused.

In Fig. 1, the device comprises a singlerespect, for each device maycomprise as many separate parts suitably secured. together, as may bedesired.

In the modifications shown in the drawings, the device is constructedpartly out of sheet metal and'partly out of wire, which is found to beeconomical and more durable under some circumstances and requires amachine simpler in some respects to manufacture than the machine formaking the device in Fig. 1.

In Fig. 1, B represents the body member and G the spring member which isbent over the body member and is normally separated therefrom. The bodymember is bent longitudinally of its length to form an arch or rib andthis rib is slotted transversely at D, leaving two upwardly projectingresistant portions E. The remainder of the body and spring members ispreferably slotted longitudinally at F and the outer.

end of the spring member is provided with the wire engaging loop or bendG, which is pressed out of the metal and is adapted to pass into theslot D between the projecting members E, so that when a wire H isinserted longitudinally beneath the members E and through the wireengaging portion Gr, said wire will be gripped at at least three pointsof contact and held in position by the retractive force of the spring.The device is adapted to be secured to the support A. as by means of thescrews J.

In Fig. 3, the body member is formed out of sheet metaland is bent orfolded longitudinally along the line K to form an arch or rib into whichthe conductor is inserted lOlL:

gitudinally. This rib is provided with the slot L and the spring memberis formed out of wire, the ends of which are secured in the sockets P onthe body member. The outer end or loop Q, of the spring member forms theWire engaging portion which is adapted to enter the slot L on the bodymember.

In Fig. 5 the construction is substantially like that in 3, except thatless sheet metal is provided, and the main members R of the wire portionare made longer, so that the device is; lighter and cheaper tomanufacture.

In Fig. 6, the body member S comprises a fiat sheet of metal having thesockets T for the ends of the spring member U. The other end of thebody-member is provided with the hook or tongue V forming the rcsistantmember. In this modification the conductor H is adapted to be insertedtransversely instead of longitudinally, and the side loops of the springmember are adapted to pass on each side of the resistant member V. o

I claim and desire to obtain by Letters Patent the following:

1. A spring fastening device, having a body member and a spring member,each provided with a transversely extending oppositely bent wireengaging portion adapted to receive and hold a conductor at at leastthreepoints of contact when said conductor is thrust longitudinally of.the device into.

said portions.

A spring fastening device, having a body member provided with anupwardly and longitudinally extending projecting resistant portion alsoextending transversely of the same, and a'spring member having a;transverse wire engaging portion adapted to cooperate with saidresistant portion to clamp a conductor at at least three points ofcontact when said conductor is inserted longitudinally through theresistant portion and wire engaging portion.

3. A spring fastening device, having a body member bent longitudinallyof its length to form an arch adapted to bridge the body membertransversely, said arch having a transverse slot and a spring memberhaving a Wire engaging portion extendbeing provided with a longitudinalrib open at one side and slotted transversely, the other having aprojecting wire engaging portion adapted to cooperate with said rib toclamp a conductor at at least three points of contact in the same plane.

(3. A spring fastening device having a sheet metal body member providedwith a transversely extending upwardly projecting resistant portionhaving a transverse slot, and a spring member formed out of wire andhaving a wire engaging loop adapted to enter said slot and cooperatewith the said resistant portion of the body member.

In testimony whereof I have signed this specifieatioi'i in thepresenceof two subscribing witnesses.
